JEROME R. GEORGE, OF WORCESTER, MASSACHUSETTS, ASSIGNOR- TO -MORGAN CONSTRUCTION COMPANY, OF WORCESTER, MASSACHU- SETTS, A CORPORATION OF MASSACHUSETTS.

GAS-PRODUCER.

Specification of Letters Patent.

Patented Oct. 24:, 1905.

Original application filed July 10, 1903, Serial No. 164,934. Divided and this application filed August 3, 1904. Serial No. 219,35 7.

To all whom it may concern.-

Be it known that LJEROME R.GEoReE,a citizen of the United States, residing at Worcester,

in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvementin Gas-Producers, of which the following is a specification, accompanied by drawings forming a part of the same, the whole being a division of my application, Serial No. 164,934, filed July 10, 1903.

In the draWingsFigure 1 is a vertical sectional view of the lower half of a gas-producer, showing the means for supplying and distributing a blast of air to the gas-producing chamber; and Fig. 2 is a transverse sectional view through the air-passages leading to the gas-producing chamber on line 2 2, Fig. 1.

Similar reference-figures refer to similar parts in both the views.

The object of my present invention is to provide an improved apparatus for supplying an air-blast to the gas producing chamber; and I accomplish this object by the construction and arrangement of parts, as hereinafter described, and pointed out in the annexed claims.

Referring to the accompanying drawings, 1 denotes the lower portion of a chamber of a gasproducer inclosed, in the present instance, by circular walls 2.

3 denotes the fuel in the gas-prod'ucer,which is admitted to the top of the gas-producer (not shown) by any suitable means.

Air is admitted to the bottom of the chamber 1 through a horizontal conduit 4, which is divided by a horizontal partition 5 into two air-passages 6 and 7, which communicate at their outer ends with a common chamber 8, into which a blast of air or steam is supplied through a pipe 9, communicating at its lower end with the chamber 8and at its upper end with a drum 10, to which air is admitted through openings 11 in its top. Entering the top of the drum and concentric therewith is a steam-pipe 12, through which a jet of steam from a convenient source of steamsupply under pressure is delivered from the mouth of the pipe 12 within a series of short cone-shaped pipes 13, between which currents of air are induced through openings 14 by force of the steam-jet, and the mingled current of steam and air is admitted through the pipe 9 to the chamber 8 and into the passages 6 and 7 The passage 6 communicates at its inner end with a vertical pipe 15, inclosed in and concentric with a pipe 16, forming an annular passage 17 through the pipe 16, which terminates beneath a conical hood 18. The

narrow pipe 15 extends through the apex of the conical hood 18 and terminates beneath a smaller hood 19. The pipes 15 16 and hoods 18 and 19 are concentric with the bottom of the heating-chamber 1, and the blast of mingled air and steam which passes through the annular space 17 in the pipe 16 is delivered beneath the hood 18, by which it is diverted radially outward to the outer edge of the hood, between which and the walls of the heating-chamber it passes upward through the incandescent mass of fuel 3. The current which is conducted through the inner pipe 15 is delivered beneath the smaller and upper hood 19,-by which it is radiallydiverted until it flows upward around the edge of the hood 19 and near the center of the heating-chamber. By this diversion of the currents of air and steam oxygen is supplied through the pipe 16 to an annular zone of fuel lying next the Walls of the gas-producer, and through the pipe 15 oxygen is supplied to the fuel in the center of the gas-producer.

Between the chamber 8 and the air-passages 6 and 7 I place a sliding damper 20, supplied with a handle 21 outside the chamber 8, by which the position. of the damper may be varied to control the flow of air through the passages 6 and 7, so that when the damper is raised to its highest position the flow ofair will be shut oif from the passage 7 and allowed to pass freely through the passage 6, and when the damper is in its lowest position the air-passage 6 will be closed and the passage 7 fully open, and by varying the position of the damper 20 between its highest and lowest position the flow of air through the air-passages 6 and 7 can be controlled by the operator as may be necessary in order to maintain a uniform combustion of fuel in the two sections of the heating-chamber supplied by the pipes 15 and 16.

What I claim as my invention, and desire to secure. by Letters Patent, is

1. In a gas-producer the combination with a heating-chamber, of an air-cond uit leading to the bottom of said heating-chamber and comprising independent passages, means whereby the air is supplied to said chamber by said passages at different radial distances from the center of said chamberand means for varying the relative flow of air in said passages.

52. In a gas-producer, the combination with the heating-chamber, of a pair of air-distributing conical hoods concentric With the heating-chamber and of difi'erent diameters, Whereby air is supplied to said chamber at different radial distances from the center, independent air-passages leading to each of said hoods, and means for controlling the flow of air in each of said air-passages, substantially as described.

3. In a gas-producer the combination With the heating-chamber, of a multiplicity of airpassages leading to the bottom of the heatingchamber, means at the delivery-openings of said passages whereby the air passing through said difierent passages is delivered at different radial distances from the center of'said chamber and means for varying the relative flow of air in said different passages.

4:. The combination With the heating-chamber of a gas-producer, of an air -chamber, means for supplying a blast of air under pressure to said chamber, independent air-passages leading from said air-chamber to the bottom of said heating-chamber, means for varying the relative flow of air in said independent passages.

5. The combination with the heating-chamber of a gas-producer, of an air-chamber, means for supplying air to said chamber, an air-conduit leading from said chamber to the bottom of the heating-chamber, said conduit being divided into two adjacent and independent air-passages, a damper for controlling the flow of air from said chamber through said passages, substantially as described.

6. 1n the air-supply of a gas-producer, the combination with two independent air-passages leading to the bottom of the heatingchamber, of a common damper arranged for the joint control of both the air-passages, substantially as described.

7. The combination with the heating-chamber of a gas-prod ucer, of two independent airpassages for the supply of air to said chamber, separate means for distributing the air supplied by each of said air-passages, a pipe leading from one of said air-passages to one of said air-distributers, and a second pipe inclosingsaid first pipe and forming an annular passage from the second air-passage to the second air-distr'ibuter, substantially as described.

Dated this 1st day of August, 1904.
